Don't blow up.

When a training tire varies drastically from a race-day tire, it will have negative effects. Ideally, you want a training tire that mimics the suppleness of a race tire but doesn't explode at the first sign of road debris. That's why Maxxis makes the Detonator Tire with two different compounds.

The soft silica compound on the outer edges provides the same supple, confident cornering you expect from a race tire, while the center is designed for durable use over long training miles. The tire's casing also incorporates Maxxis' Silkworm technology, which stretches from bead to bead for added puncture- and tear-resistance that doesn't engender a weight penalty or a harsh ride.
